H. 1 scHRECK TRAVELINGTILTING TABLE Filed March 27, 1950 5 Sheets-Sheet 5 to the raising andlowering of the' table, thereis provided a pneumatic devicewhich willVnow be described. -At the forward end'of the carriage- 14l upon eitherside of the guides 35, there aredisposed the cylinders which are adaptedto receive the hollow plunger-s 51.

the clamping devices comprising collars 54 and bolts 55 to provide afluid tight fit between-the walls of the plunger 51 and those of thecylinder 50 at the upper end thereof. Since kthe table 15 moves throughan arcuatefpath when tilted, and

- the `plungers 51 move verticallyV in the cylinders 50,'

there is provided a relatively loose connection between them whichcomprises the shafts 56 which occup'ycthe` hollow tapered interior ofthe plungers 51 and restat their lower ends upon theA seat pressed air,is supplied Yto Ythe cylinders 50 by means of the ycompressor60carriedby the carriage 14. The air isL forced into the balancing tank 61through the conduits 62. and'from there it mayrpass to andfromthevcylir'iders 50 through the conduits` 63. ByY means jof Ysuitablevalves and controls, the fluid may besupplied to' the tank 61 andcylinders 50 at the proper pressure and vented therefrom insuch manneras' to balance 'the weight of the table 15 andv they articles carriedthereby so as torelieve the lifting'mechanism from undue strain.,l

The table 15l is provided with the driven. rollers 65, the reduced endsof which are mounted in the bearings 66. The rollers 65 areA operativelyconnected by means of the bevel gears contained in housings 67 to thelongitudinal shafting 68.V This shafting, 68 is drivenby means of Vthemotor 69 throughthe gearing encased in the housing 70. The motor 69andgearing 70 are carried b y a lateral extension 71 ofthe 'rear endofthetable `515". "A platform or run-way 72 may be provided above theshafting 68, as illustratedA in Figures 4 "and 5. The bearingsfor therollers65 are carried by the side frames 75 and 76,*which are fr"mounted on the beamsf44. Above the level of the rollers 65', the Ysideframe 75 is provided'with the guide or guard 77 and the opposite sideframe v76y adjustably and Mresiliently carries Ythe v'movable `side,guide or guard 78. Atfintervals the side frames 76 are provided withupstanding enf-j larged portions `v80 which alternatewith the rollerbearings 66; At correspondingintervals there is rigidlysecured to theside guard 78 the members 8l which are adapted to be insertedfin therecess 82 in the portions 80. The members 81 'are provlded withV hollowprojecting portions 8 3 which V`are adaptedA to enter the reduced recess84 of the 'portion so. The'part a3 of the member si V.is provided withthe recess 85 Iwhich is adapted to contain the coily springl 86 whichbears against' the wall 87 of the portion SOand the innerwall 88 oftheelement 81 and tends'to constantly urgel i Vthe members 80 andy 81apart. 'NA Ybolt 90 having va head`91 ece'ivedin the recess 92 ofthe'member 81, passes through the opening 93 in the `wall 88, throughthe recess or chamber 85 and through the` opening 94 inthe wall 87.Threaded upon the projecting outer ends of the bolts are the nuts 95.:These `bolts90 serve to secure the guide 78 to the ,portions 80I oftheside .frames Suitable packing .52 is clamped between the rings 53 bymeans of 76 against the compression of the spring 86 and by the'propeiadjustment of the nuts 95 the nor- '.mal position ofthe side guard.78may'be determined.A It will thus be seen that the outer side guard 78 isprovided with buffer or cushioning mechanism by'means of which anyshocks that it might. sustain incidental to the manipulation of articles`carried by the table may be absorbed and dissipated.

yFor the purpose of shifting the billets or other articles carried bythe table from side to side Vthereof and also for rotating or invertingthem Vfor their proper vpresentation to the roll passes, there isprovided the manipulating mechanism which will now be described. Atsuitable intervals the' side beams 44 of the table 15 are providedwithvthe castings' 100 which extend from one of these beamsto the other.vThese castings are provided with bearings 101 and 102 which are adaptedtorotatably `receive the longitudinally extending rock shafts 103 and104 respectively. Keyed to the rock shaft 103 atl suitable intervals arethe collars 105 of the swinging members 'or levers 106. -The rock shaft103 is susceptible of rotation through an arc which will permit themember 106 to' move from the solid line position to the dotted lineposition shown in Figure 5. These limits of movement correspond tothe'rpositions designated C and A in Figure 12.y Y

The member 106 is adapted to pass through an opening inthe block 107which is mounted for reciprocation alongthe member 106. The member orblock 107 is preferably provided with the stepped portion 108. Pivotallyconnected to the :block 107 vas at 109 is the link 110 which ispivote'dat its opposite end to the crank arm 111 asV atv 112. Thecrankarm 111 is provided with a sleeve portion 113 which is keyed to theshaft 104. When` both the shifting member 106 and the crank arm 111-arein-their lowermost positions the various elements are'disposed as shownin .the full line Vposition in Figure 5, in which the gear 1'15vv whichis adapted to mesh with the segmental gear 116 carried` by the crank 117which is ymounted upon the frame of the table r15 for pivotal movementas at 118. The crank 117` 1s provided with a pair of spaced arms 119which are pivoted to the connecting rod 120 as at 121.

Mounted in bearings 122 carried by the carriage 14 is 'the crank shaft123 provided with the crank" ,portion. 124 which is vpivotally connectedto the left hand end of the connecting rod 120 as seen in Figures 1 and3. `Crank shaft 123 is driven by the motor 125 by means of the worm gear126 and is controlled by the magnetic brake 127. The rock shaft 104 issimilarly provided at its right hand end as shown in Figure 2 with thebevel segmental gear 128 which meshes with the gear 129 carried by thecrankf130 which is pivoted to the frame of the table as at 131, and isprovided with the arms 132 which are pivotally connectedtothe'connecting rod 133 `as at 134'. A

Acrank shaft 135 is mountedvin bearings 136 carried by the carriage 14and is'provided with the crank portion 13,7Y which is pivotallyconnected to the opposite vend of the connecting rod 133.

shaft 135 is Vdriven by the motor 13a through thel Y 1,928,195 wormgearing 139 and is oontroneooy Y,the *magnetic'brake 140. It will thusbe seen that by meansof lthe mechanismljust described, the rock shafts103 and 104 may be independently rotated i'n'either direction and 'atany piositiozjlofV the tilting Vtable 15. n n n In'Figure-IZ, lettersAand B indicateV the limits of movement of the shifting member 106between whichA the kick-up member 107 can-operata numeral ,150. In,`Figure the "manipulator -is` shown in its lowermost retracted position.-Figure Figures 6, 7 and 8 illustrate some of theV move-V ments of theshiftingmember 106 and the kickup member 107 `when handlinga piece offlat work, such as a slab or plate, indicated bythe 'l -illustrates theuse of theshifter member'106 alone for raising the-slab 150 from theposition shown in Figure 6 toone in which it is resting upon its edge.
